quantity. The softening of the solder wire above the soldering iron will also cause the solder to drop and strike the can before striking the iron. The solder will be de flected and bent to one side. or the other of the can, or it it strikes the iron at all, it will be improperly directed, and therefore, improperly placed .on the can and the seam will not be filled. These defects are obviated by the construction which I- have devised and I have found in actual practice that solder fed by the mechanism now to be described will be fed in precisely the proper amount, will be directed to precisely the proper place on the can, that there will be no waste of solder and that the feed of solder can be accurately regulated for each class of cans.

In the drawings, Figure 1 is a side elevation of the soldering end of an end-seam machine or floater, such as is shown in my prior application above referred to; Fig 2 1s a transverse section of a part of the structure shown in Fig. 1, the section being taken on the line 22. Fig. 3 is an enlarged section of the casing inclosing the solder teed wires and idlers; Fig. 4 is an-cnlarged fragmentary detail section of the casing tran verse to Fig. 3, the feed roll being partly in section; Fig. -5 is an enlarged fragmentary detail {view showing the feed roll and its ratchet gear in elevation; Fig. 6 is a fragmentary enlarged perspective view of the solder iron shown in Figs. 1 and 2; Fig. i is a perspective view of a modified form of solder iron.

Certain portions of the apparatus, namely. the supporting framework, the can con veycr, the yielding trackway or bed and the magnetic tractors for increasing the adhesion of the cans to the track and compelling them to roll beneath the solder iron. are constructed as described in my prior application. It is, therefore, sutiicient to say that the f amework of the floater consists of the vertical standards 2, opposed to each other at intervals on opposite sides of the path of movement of an endless can con veycr. These standards are tied to Lzltll other in any convenient manner, as by the longitudinal angle irons 3 and 30. Cross braces 4, 5 and 6, connect the standards transversely Supported on transverse irons 7, are the .ading rails or traclnvays 9, prcferably of rubber tubing supported in chan- I nel IIOHS, 10, attached to the irons, I. by brackets 8. On this tubing the calls roll and are supported as they pass beneath llasoldering irons. The transverse supports 2 are oppositely inclined from the middle to fornrtrackways for two rows of cans. one on each side of the machine. Longitudinal guide rails 11 are supported above the trackways against which the outer ends of the cans engage, while angle irons, 12,- attached to a middle channel iron, 13, form guides for tl.e inner ends of the two rows of cans. The channel iron 13 forms a irackway for the links, ll, of an endless conveyer chain having at. intervals upstanding plates H which are riveted to a cross bar, 15, having opposed outwardly and downwardly ext-end; ing ends which contact with thesidcs of the cans to roll them along the traclnvays and beneath said soldering irons. This endless convcyer lat is moved in one direction in any desired manner. Located beneath the path of movement. of the cans on both sides of the centeris a series of magnets 16, over which 'the cans roll, and which act as magnetic tractors, increasing the adhesion of the cans to the yielding bed rail, 9, and causing the cans to roll beneath the soldering irons as they are moved along by the conveyor blades 15. It is necessary to an understanding of the operation of my device that this fact be kept in mind: that the cans are rolled positively beneath the fixed soldering irons 18.

Just above the bars 11 are located the soldering irons 18. These are angular in cross section, one flange of the angle iron extending downward at a slight inclination toward the median line of the machine, the other i'langc of the iron extending outwardfrom the upper edge of the iron. In the space formed between these two angular flanges is located the gas burner tube or other heater, 19, which is connected by the pipe to any suitable gas supply. It will be seen that-the heat from the burners is conserved by the uppermost flange of the iron and that the tiame and heat of the burners are directed chielly against the inside face of the downwardly extending flange. It will also be seen that the upper flange acts as a shield tending to prevent the passage of heat directly upward from the burners and so into contact with the solder, as will be later described.

In order to supportthe soldering irons I provide the vertically extending supporting bars, 2-2, which are bolted at their lower ends to the upper flange of the solderin iron, and at their upper ends are longitudinally slotted as at 23. A bolt 24 passes through the slot and engages with airangle iron 2.) which is supported by the transverse blfll'CS 5. Through the bolt 24 the bar 23 may be raised or lowered and clamped in any adjusted position, thus vertically adjusting the soldering irons. Also attached to the upper flange of the soldering iron is the transverse upwardly inclined adjusting bar .67. whose ontcr end is slotted as at 28, A bolt, 23), passes through the slot "2S ml engages a longitudinally extending angle iron 30, which is bolted to the standards 2.

the s ldering irons a shown clearly in Fig.

beveled face of th soldering irons. Each f the soldering irons: preferably has a beveled face. The casing 56 is. upported by transver e depending strap iro 57. which are bolted to the angle irons as shown in Fig. l. The casing may be also supported by the longitudinal angle irons 53 which are supported on the transverse irons (3 as shown in Fig. 2. Of course, I do not wish to be limited to this manner of supporting the case, as any other may be used. but i have found this to be asimple and rigid manner of supporting the soldenfeeding mechanism.

At. their upper ends, the rods, 43. pass through the strap iron 5 and are provided on their extremity with the set nut. 60 and washer 61 .(see Fig. 2). Spiral springs, 62. are interposed between the washer (ll and the longitudinal horizontal flange. 5 of the iron .3 (see Fig. 2 A sleeve (33 surrounds thesprings, the washer 61 being larger than the sleeve. These springs lessen the no se which would otherwise. occur caused by the falling of the rods, As the blades pass the lower ends of the rods the springs take up the shock of this falling mot'ement. V

The sleeves. 63, act as stops to the washers 61. the nuts permitting the washers to be adjusted on the rods 43. The higher the washer is on the rod 423, the gleaierthe dis- The adjustment of the rods 43 regulates the distance through which the rods -13, with theii rcarwardly bent portion ll, shall descend between the blades 15 after each one of the blades passes the junction of the arm ll and the rod 43. The junction of the rod 43 with the arm 44 is rounded as shown in Fig. 1 to permit the gradual lowering of the rod 43 as the blade 15 passes. It is on this downward movement of the rods 43 after the blade 15 has passed that. the pawl 41 1; "'es over the ratchet 38. Hence, by regulating the extent of the downward movement of the rods I 43, the amount of feed can be also precisely regulated. The feeding movement.oft-nur e. I

takes place upon the contact of blades, 17

with the lower bent ends of the rods 42''. and L the. consequent raising of these rods. .\s the rods 43 are raised the pawl engages with the ratchet of the roller. and all the wires. T. are fed forward a definite amount. As the wires are spaced longitinlinallv a certain definite distance along the soldering iron.

and as the feed is controlled bv the raising of the rod 43 through the blade 15. it will be seen that the solder is fed form-1rd before E each of the cans and that it is thus fed forward against the face of the iron just previous to the passage of a can beneath that particular solder point so that the solder is melted. flows down the iron to the edge 7 5 thereof, and is immediately engaged by a "2, so that the solder delivered against. the

can. The solder flows beneath the edge of the. soldering iron and as a consequence the irons have a wiping soldering action against the seam of the can, which forces the solder into the seam and practically precludes the possibility of a seam being left- .unfilled or unsoldered.

lVhile I may use a soldering iron with a beveled edge. such as shown in Fig. 6. and find that such a soldering iron etl'ective in practice. yet in Fig. 7 I show a form of iron wherein the drop of molten solder is positively guided down to one pointon the iron so that there is no chance of the solder spreading over the face of the iron and thus not being properly distributed upon the can.

solder guiding portion by grooving the innerface of the iron tS-l, said grooves (16 being conjoined with each other at the lower edgeof the iron and diverging from each other as they extend upward. Solder applied at any portion of the wedge-shaped tonguetGS. will flow downward until it reaches the extreine lower point of the tongue, the grooves (16 on both sides preventing the solder from spreading away from the tongue, and the point of the tongue directing the solder in a drop upon the can itself. This is particalarly advantageous inasmuch as the drop of solder collected at the lower end of the tongue will be intercepted by the advancing can and will be rolled along with the can beneath the edge of the iron in the manner before explained. Thus the solder will be properly distributed along the seam and the lower edge of the iron will be kept bright and tinned.

The operation of my invention will be obvious from this description. The conveyer H with its blades 15. rolls the can along the traclcwav towards the soldering device. Just before one of the blades 15 reaches the entrance end of the soldering irons. the blade wi l strike the lower end of the arm 44 and will. of course, vertically lift the arms 44 and the rods 43. As they are lifted the feed rollers 23 will be turned and the soldering wire 4? fed forward about. an eighth of an inch for ordinary sized cans. The solder will be projected against the face of the iron just in advance of a can as before explained,
